Because of how the display works, you always see the teleporters on the edge, and because they are all painted Orchid on default, makes them all look near identical. I propose that all the teleporters default colors be changed so they’re easier to differentiate
Regular Teleporters - Orchid
Staff Teleporters - Teal? I don't know
VIP Teleporters - Yellow
Regular Powered Teleporters - Blue
Death Teleporters - Red (includes the powered death teleporter)
Recall Teleporters - Lime Green or Olive
